Pole-tip



UNTTED STATES PATENT OEEICEO ISAAC It. GILBERT, OF CHARLESTOWN, INDIANA.

POLE-TIP.

SPECIFICATION forming part of Letters Patent No. 238,385, dated March 1, 1881.

Application iiled November 27, 1880. (No model.)

To all whom it may concern:

Be it known that I, ISAAC R. GILBERT, of Charlestown, in the county of Clarke and State ofIndiana, have invented certain new and useful Improvements in Pole-Tips; and I do hereby declare the following to beafull, clear, and exact description of the same, reference being had to the accompanying drawing, and letters of reference marked thereon, which form a part of this specification, and in which is represented a perspective view of my tip secured to a pole.

While it is evident that my invention may be applied to the tongue ot' any kind of vehicle, yet I more especially design it fora certain class ot' agricultural implements-such, for instance, as sulky-plows, seeding-m achines, Ste. lt has hitherto been customary, in the manufacture of the above-named class of machines, to make the tongue or pole ot' sufticient length to accommodate horses of the largest size, and as it is essential to have them as near the machine as possible it follows that when those of small size are used they would be too far from the machine to give the best results of' their work. To obviate, therefore, this ditiiculty, is the object ot' my invention 5 and it consists in the peculiar construction of an adjustable tip, which will both protect the pole from wear of the neck-yoke and adapt it to horses of Various sizes.

To enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation.

B represents the tip, which consists of a sleeve or ferrule, of suitable length, made to iit the pole A. The under side ofthe tip is slotted longitudinally, and from each side ot' this slot project the wings c c, thus forming a lengthened slot whose sides are parallel from the un der side ofthe pole to the lower edge of the wings. The width of the slot should be sut'- iicient to enable the wings to be compressed by means ot' the bolt f and nut d, and thus adapt it to fit poles of unequal sizes, and be rmly secured thereon, either farther from or closer to the outer end thereof.

It will be particularly observed that both the inner and outer ends of the sleeve B project a suitable distance beyond the wings, in order to form rub-plates 7 g g', to protect the pole from wear of' the neck-yoke and the ring attached to the same. As the wear on the rear end ofthe tip will be on top this part of it may be beveled, as shown in the thawing, which incline or bevel I prefer to extend to the bottom ofthe wings c c, while the opposite end of said win gs are made straight or perpendicular from the under side of the sleeve. I find it also desirable to strengthen the win gs by casting their outer edges on their iiat sides with a raised border, which border should extend ashort distance up the front sides ofthe tip, as seen at IL, with a slant backward to serve as an additional stop for the ring` ofthe neck-yoke to bear against, while on the rear end this border should extend around the same from Wing to wing.

I am well aware that, broadly speaking, a sleeve provided with wings with a slot between them and a screw-bolt for compressing the same is not new, as such a device has been used for clamping wood, &c., and therefore lay no claim to such a thing per se; but

What I do claim, and desire to secure by Letters Patent, is

l. The within-described pole-tip, consisting of an adjustable ferrule or sleeve having wings c c and stop h, and an extension in front and rear of said wings, all substantially as and for the purpose set forth.

2. 1n combinationwith a pole or tongue, the sleeve B, having wings c c, and formed with an extension in front and rear thereof, and adapted to be adjusted and tightened on the pole, all substantially as herein shown and described.

In testimony that I claim the foregoing as my own I afiix my signature in presence of two witnesses.

Witnesses: ISAAC It. GILBERT.
